WikiProject assessment

The following system is used to assess the quality of a Wikipedia article. The system is based on a letter scheme that reflects principally how factually complete the article is, though language quality and layout are also factors.

The quality assessments are mainly performed by Wikipedia editors, who tag Talk pages of articles; set the class tag for assessment based on other Talk tags or based on editor-selected values. Editor assistance tools like Rater apply automated ORES or Lift Wing article assessments, offering a prediction based on structural characteristics of the page (e.g. sectioning and references) that correlate with quality, for the class tag. These tags are then collected by a bot, which generates output such as a log and statistics. For more information, see Using the bot. In 2023, project-independent quality assessments were introduced, so editors only have to rate an article once and it applies to all associated projects.
